--- Begin Message ---Package: libmutter0g Version: 3.18.2-1 Severity: important While I cannot reproduce this reliably, calls to “xclip” (that I use through the “pass” package) sometimes cause the gnome-shell Wayland compositor to become unresponsive and take 100% of one CPU core. Xwayland had a relatively high CPU usage during this time, but nothing close to gnome-shell: around 10%~20% of one core. This is especially bad as it stalls any interaction with the compositor, including VT switching, and I found no way of recovering except by killing the gnome-shell compositor and thus losing all of its clients. In addition, after some time, it fills gigabytes of various log files with messages like: Jan 12 13:23:22 faye gnome-session[1707]: (gnome-shell:1715): mutter-WARNING **: Error transfering wayland clipboard to X11: L'opération a été annulée While it might not be entirely representative of how gnome-shell codes executes in this condition, I managed to use gdb to get the following backtrace, confirming once again that the issue lies within the XWayland clipboard handling: 0x00007fa67d97d08d in writev () at ../sysdeps/unix/syscall-template.S:81 #0 0x00007fa67d97d08d in writev () at
